I’m replacing every trace of ZEGOCLOUD in my existing Flutter codebase with LiveKit Cloud and need someone who has already shipped production workloads on this stack. The app is live on both iOS and Android, so the migration must remain fully cross-platform. Scope of work • Swap the current ZEGOCLOUD SDKs for LiveKit SDKs and wire them into the existing Flutter UI. • Enable and thoroughly test Live Streaming, Video Conferencing, and Real-time Chat—each feature must behave at least as smoothly as it does today. • Stand up a tailored LiveKit Cloud configuration (custom room settings, token generation, recording options, etc.) and connect it to my backend. • Update any server-side endpoints or web-socket flows so authentication, participant events, and media routing work seamlessly after the switch. • Conduct end-to-end testing on real devices for both iOS and Android, fix edge-case glitches, and hand back a build that clears the App Store and Play Store review gates. Acceptance criteria 1. Flutter project compiles cleanly with the LiveKit SDK and no residual ZEGOCLOUD imports. 2. Live Streaming, group calls, and chat all function with <300 ms latency on average in my test environment. 3. Custom LiveKit settings (e.g., adaptive simulcast layers, region routing) are active and verifiable via the LiveKit dashboard. 4. All backend changes are delivered as merge-ready pull requests with clear documentation. 5. Final builds pass my smoke tests on both iOS (latest iPhone) and Android (mid-range + flagship). Tools you’ll likely draw on: Dart/Flutter, LiveKit SDK, REST/web-socket APIs, Firebase/Node (our current backend stack), and Git. If you’ve executed a similar migration before, especially under a tight deadline, I’d love to see it.

Migrating a live Flutter app from ZEGOCLOUD to LiveKit is less about swapping SDKs and more about making sure the real-time behavior stays invisible to your users during the transition. I’d start by mapping the current ZEGO implementation—streaming flows, room lifecycle, chat events, token handling, and participant state management—so the LiveKit integration mirrors existing behavior before introducing any optimizations. From there, I’d replace the client SDK layer in Flutter, wire it into the existing UI, then update backend token generation, room management, and websocket event handling to match LiveKit’s architecture. The part that usually causes issues is reconnect logic, participant state synchronization, and device-specific media behavior. I’d validate those early on real iOS and Android devices rather than leaving them until the end. I’d also enable adaptive simulcast and region-aware routing to help maintain latency targets under varying network conditions. I’ve handled production Flutter integrations involving real-time communication and backend event synchronization, so I’m comfortable working across both the Dart and Node/Firebase sides of this migration. Ready to dig into the existing implementation and start with an audit of the current ZEGO flows.

Hi, Replacing a real-time communication stack isn't just about changing SDKs—it's about making sure users never notice the migration happened. My focus would be preserving your existing Flutter experience while carefully replacing every ZEGOCLOUD dependency with LiveKit, validating streaming, calls, chat, authentication, and backend events before anything reaches production. I've built and maintained production Flutter apps like Sync My Schedule and Husk Network, where stability, API integrations, and cross-platform reliability were essential. I'm comfortable working with Firebase, REST/WebSocket flows, Git, and delivering clean, merge-ready code with proper testing. If your priority is a smooth migration with minimal risk, I'd be glad to help make it happen.

✅ 1. Where is ZEGOCLOUD used now: live rooms, group calls, chat, recording, or call invites? ✅ 2. Should LiveKit tokens be generated through your existing Firebase/Node backend? ✅ 3. Which LiveKit Cloud settings are required: region routing, simulcast, adaptive stream, recording, or webhooks? I’d first map every Zego import, room event, participant role, and websocket/backend dependency before replacing SDKs. Risk sits in token claims, reconnects, audio focus, app lifecycle, chat parity, and store permissions. Latency under 300 ms must be verified on real devices against the selected LiveKit region. PRs can be split into SDK removal, backend token/events, Flutter wiring, and QA fixes.

Hi! SDK migrations on a live production app are riskier than greenfield builds — the real challenge isn't swapping the imports, it's making sure every edge case in your existing UI (reconnection logic, participant event handling, background audio on iOS) behaves identically or better after the switch. That's where I'll focus most carefully. I'll replace all ZEGOCLOUD SDKs with LiveKit Flutter SDK across iOS and Android, wire up Live Streaming, Video Conferencing and Real-time Chat to match current behavior, configure LiveKit Cloud with custom room settings, token generation, simulcast layers and region routing, update all backend endpoints and WebSocket flows for auth and participant events, and deliver clean merge-ready PRs with documentation. End-to-end tested on real iOS and Android devices, builds passing App Store and Play Store review gates.

Hi, Your migration requires more than replacing SDKs—it needs a seamless transition that preserves functionality, performance, and stability across both iOS and Android. I can handle the complete migration from ZEGOCLOUD to LiveKit Cloud, including replacing all SDK integrations, updating the existing Flutter UI, configuring LiveKit Cloud (rooms, token generation, recording, adaptive simulcast, and region routing), and integrating it with your current Firebase/Node backend. I'll also update the server-side APIs and WebSocket flows for authentication, participant management, media events, and room lifecycle while ensuring there are no remaining ZEGOCLOUD dependencies in the project. Before delivery, I'll perform end-to-end testing on both platforms, verify live streaming, video conferencing, and real-time chat performance, resolve edge cases, and provide merge-ready source code with clear documentation. The goal is a production-ready build that meets your acceptance criteria and is ready for App Store and Play Store submission. One quick question: Is your current backend already responsible for generating ZEGOCLOUD tokens, or would the LiveKit token service need to be implemented from scratch as part of this migration?

Replacing ZEGOCLOUD with LiveKit in a live Flutter app requires more than swapping SDKs—the signaling, token flow, media lifecycle, and backend integration all need to behave identically so users don't notice the migration. I would first map every ZEGOCLOUD dependency, then migrate streaming, video conferencing, and chat to the LiveKit Flutter SDK while preserving your existing UI. Next, I'd configure LiveKit Cloud (rooms, tokens, recording, region routing, adaptive streaming), update the Firebase/Node backend, and remove every remaining ZEGO reference before running end-to-end testing on iOS and Android. The biggest challenge is maintaining stable real-time communication while replacing the underlying media stack. I would validate participant events, reconnection logic, audio/video quality, and backend authentication with granular pull requests and documentation throughout the migration. If portfolio examples are requested, please remind me to attach relevant Flutter real-time communication projects instead of inventing them. Are you currently using LiveKit Cloud only, or do you also have server-side components (token service/webhooks) that need to be migrated?
